428 volumes from the King's Library either destroyed or damaged beyond repair; the museum had duplicate copies of 265 of these elsewhere in its collections. In addition a further 1000 volumes from the King's Library were in need of repair. The rest of the collection was moved to a safer part of the building, and finally evacuated from London to the Bodleian Library in Oxford in 1943. Repair work to the gallery was finally carried out in 1950–1951. At the British Library, 1997 to present In the 1970s preparations began for the move of the museum's book collection to the newly established British Library. The museum's Trustees argued that the King's Library should remain where it was, but were unsuccessful in preventing its transfer to the new institution. The collection is now housed in the King's Library Tower, a six-storey glass and bronze structure in the British Library's entrance hall; the tower was designed specially by the building's architect, Colin St John Wilson, and also contains the Thomas Grenville collection. Items from the collection remain available for reading by the public. The collection's old home at the British Museum, restored in 2000–2003, is now known as the Enlightenment Gallery and houses a permanent exhibition about the Age of Enlightenment, opened to celebrate the museum's 250th anniversary in 2003.

In other words, this was a working library rather than a showpiece, although it did contain some notable rarities. These include a Gutenberg Bible and many English incunabula, including a copy of Caxton's first edition of The Canterbury Tales. The purchase of Thorkelin's library meant that there was a notable collection of over 2,000 works on Scandinavian language and literature. The collection also includes the first four Shakespeare folios. The oldest-known catalogue of the library was compiled in 1769. The Bibliothecae Regiae catalogus, a catalogue of works organised by author, was published in five volumes between 1820 and 1829, its compilation being overseen by Barnard. A hand-written subject catalogue also exists; work on this subject catalogue may have started in the 1790s, and it was kept updated through several subsequent decades. The library's pamphlets were catalogued for the first time following the Library's move to the British Museum. In 1769 the library contained
